[rt-users] Accessibility of RT for screen reader users?

The coloured items are links but they are not <h> tags. Their attributes
are defined using CSS classes.

I tried tabbing through the page and you have to tab through every item in
every menu before you get to the body of the ticket. Once in the body of
the ticket tabbing jumps from link to link, and tickets typically have many
of these.

Of interest may be RT's built-in keyboard shortcuts:

While there are shortcuts to navigate search results as well as some basic
actions (like commenting) there do not appear to be shortcuts for
navigating headings within a ticket.
